I am new to the Dreamcast scene but I am quite enjoying this little console. My first one is a Va0 it has a bba on it which I still haven't used and recently I bought a 2nd unplanned va1 in a very nice yellow housing. I also have bought a karaoke just waiting on the lazy seller to finally ship it for putting all the mods I plan to do to the va0.
Already done mod:
Rgb color changing led on the va0
2.5 Hdd or CF ( I bought an SYBA IDE to Compact Flash Adapter and an Olmaster 2.5" Hard Drive Mobile Rack to see which one I like more)
Unplanned but possible mods:
Real water cooling( I love the metal fan in the va0 but I have to admit it sounds like a little turbine and as pointless as it would be to water cool a Dreamcast I still think it would be cool.)
Internal ps2 game controller adopter ( I find the Dreamcast controller a bit awkward for me I am really used to my Xbox controller)
I don't own many games personally mainly just borrow them from a friend.
